Samples was made into thin sections with polished surface, which were uncoated. Each point of interest accumulated over 10000 counts. Measurement name: Energy-dispersive X-ray...

Samples were made into 100 μm rock slices. Points of interest were aligned to the beam and measured with φ scans +/− 25° at χ = 0°, 30°, 60° and 90°, respectively. Stepsize of φ...

The mineral phase of primary marine fibrous carbonate is supposed to be mainly controlled by the Mg/Ca of seawater during precipitation. However, fibrous Mg calcite was...

Primary fibrous dolomite has been reported in cavity systems in Neoproterozoic reefal and platformal carbonates. It is surprising to find fibrous dolomite in Miocene methane...

Samples were made into thin sections with polished surface. Each spectrum was measure by 10 loops with each one collected for 15 seconds. Measurement name: Raman...

Samples were made into thin sections with polished surface. Elements of MgO, SiO2, CaO, FeO, MnO and SrO were measured. Measurement name: Electron probe microanalysisInstrument:...

Samples were made into powder. About 1 mg was required for each sample. Results were measured by the standard phosphoric acid method. Measurement name: Carbon and oxygen isotope...

Carbon and oxygen isotope compositions of fibrous carbonate minerals were measured by an isotope ratio mass spectrometer. The results suggest that the fibrous Mg calcite from...
